Never mind, stupid mistake on my part, a missing hyphen. Duh. I feel like a fool. But, lovin it on this elderly laptop. Cannot get persistent resolution on VGA. I have the xrandr settings, have used them often. It works during a session via terminal or executing. (#!/bin/bashxrandr --newmode 1280x800 83.50 1280 1352 1480 1680 800 803 809 831 -hsync +vsyncxrandr --addmode VGA-1 1280x800xrandr --output VGA-1 --mode 1280x800) Added it to session and startup, no go as it always has in Linux Lite, Mint XFCE, Mate, etc. Nor does it work when adding , 91_custom_xrandr to /etc/X11/Xsession.d as I have also done as recently as Linux Lite 4 and Mint 19 (xrandr --newmode 1280x800 83.50 1280 1352 1480 1680 800 803 809 831 -hsync +vsync)xrandr --addmode VGA-1 1280x800 Both also work fine on Pep 8 Suggestions? No joy with arandr either. Thanks. Typing this on Pep 8.
